netdata is a web-based, real-time performance monitoring system which visualizes the system resource usage of a local Linux server (which netdata is running on) via time-series statistics. Monitored system properties include CPU usage (core utilization, interrupts, softirqs), memory usage, disk I/O (per disk bandwidth, backlog), network activities (per-interface bandwidth, packet rate, error rate, TCP/UDP protocol statistics), firewall (connection statistics), process list, and a number of application server workloads (e.g., NFS, MySQL, Nginx, Squid, Postfix), all in real time. netdata holds and visualizes time-series usage data of short time scale (e.g., less than 10 minutes), but does not (yet) store the data on a persistent storage for offline browsing. Developed in C language, netdata comes with its own web server implementation, and the backend does not require any external dependencies. The frontend web interface utilizes HTML-based Bootstrap dashboards. netdata is extremely lightweight in terms of CPU (2% of a single core) and memory usage (less than 10MB), and requires zero configuration for installation. netdata supports external plugins (which can be written in any arbitrary language) for extended charting capabilities.

One thought on “netdata”

Without persistent storage and historical views (think RRDtool), netdata is cool but limited. Worth mentioning, but until values can be stored persistently I feel Cacti (and others) will be chosen over netdata. Pretty graphics nonetheless.
